Google Maps Live View AR

Google Maps added a Live View feature that overlays walking directions on your phone's camera feed using augmented reality. It solves a specific problem: knowing which direction to start walking when you exit a subway station or step out of a building into an unfamiliar neighborhood. AR arrows appear on the actual street in front of you through the phone camera, pointing you the right way. They update in real time as you walk, so you never have to interpret a 2D map while standing at an intersection wondering which way is north. Apple Maps has a similar feature now, but Google's implementation has been available longer and works in more cities because it relies on Street View imagery. The technology uses a combination of GPS, compass data, and visual positioning. It matches what your camera sees against Street View photos to determine exactly where you're standing and which direction you face. Navigation feels intuitive rather than abstract. Instructions exist in the same visual space as the real world, not on a separate screen you have to mentally translate into physical movement. I used it in a city I was visiting last month. Following floating arrows through unfamiliar streets felt closer to having a local guide than to reading a map. Battery drain runs faster than standard map navigation because the camera and AR processing run continuously. For short walks of 5 to 15 minutes, though, the impact is manageable.
